Long Island PPTN

The NYISO Transmission Planning Advisory Subcommittee on Friday voted to recommend that the system impact study report results for Propel NY Energy’s Alternate Solution 5 project be approved by the Operating Committee.

Propel NY, a partnership between the New York Power Authority and New York Transco, proposed to build a transmission project to unbottle Long Island and enable the area to export offshore wind energy to the rest of the state as part of NYISO’s Long Island Public Policy Transmission Needs solicitation.

Propel NY’s Alternate Solution 5 proposal recently emerged as the ISO’s preferred project. (See “Long Island PPTN,” NYISO Business Issues Committee Briefs: May 24, 2023.)

System and Resource Outlook

NYISO announced it has kicked off this year’s annual System & Resource Outlook study and anticipates having the report finished by the second quarter of next year.

The outlook report forecasts system needs for 20 years, identifies challenges related to achieving New York’s policy objectives and builds upon past recommendations or observations. (See “NYISO Releases the Outlook,” NYISO OC Discusses NOPR Comments, High Temps, EDS Results.) It is part of the economic planning process of NYISO’s wider Comprehensive System Planning Process, and the ISO will spend upcoming meetings reviewing study assumptions, benchmarking results and discussing potential improvements.
